Today Google is looking to gain a little more traction in the eCommerce world by announcing that their Google Wallet mobile payment system has nearly doubled in usage since opening up the app to all major credit and debit cards in the latest update. That means in just over a month usage has completely doubled. That is a good sign.

Google Wallet hasn’t taken off quite like us, or Google expected, but that could be in part to the fact that only one US carrier officially supports the mobile payment solution. I myself have been using it with my Verizon Galaxy Nexus for months at 7-11, Airports, and Starbucks all over town and find it super useful. What about you guys?

Discover Card recently made their own little customized area and artwork of Google Wallet for their cards, and Google is hoping other credit card companies follow suite. They’re also nicely asking for anyone that wants to participate in Google Wallet contact them for details. Pretty interesting blog entry Google.

For now this technology is still extremely early and in its infancy, and I can’t see it replacing my actual wallet (or money clip as shown above) any time soon. Once we start seeing NFC stations and MasterCard PayPass terminals across the US more then it could become a truly useful feature. So far my biggest two uses are the Airport and Starbucks. What about you guys? Where do you use Google Wallet — if at all?
